ABSTRACT

A new roof ventilation system is disclosed that employs unique properties that enable it to ventilate said roof system in a simple, economical, and effective manner. This ventilation system is designed to be used in an application over roofing materials that have ribs or corrugations on their surface such as might be found on pre formed metal roofing panels. This ventilation system consists of narrow strips of material that are to be placed end to end in such a way as to form a long continuous strip. They are then covered by a typical ridge cap or other flashing material allowing the ventilation air to pass over the roofing material but under the ridge cap or flashing material. The resulting ventilation system is aesthetically pleasing, economical, functional, and impervious to normal temperature extremes and wind born materials such as rain or snow.

[0001] The present invention relates to roof ventilation, particularly to ventilation of roofs comprised of formed panels such as metal roofing.

[0002] A ventilating system for these roofing panels must first of all be impervious to temperature and moisture extremes that are normally found in these outdoor environments. It must exclude all objectionable insects and rodents from the area to be ventilated. It would ideally be easy to install without requiring extensive training to otherwise qualified roofing installers. It must be cost effective. It must, of course, ventilate the open space below said roofing panels effectively.

[0003] While applicant acknowledges other methods of ventilating said roofing systems, he asserts that all of these fail in one or more of the above mentioned areas.

[0004] Some embodiments of this new invention will now be described with reference to the drawings in which:

[0005]FIG. 1 is a side view of the vent invention.

[0006]FIG. 2 is an end view of the said invention.

[0007]FIG. 3 is a bottom view of said invention.

[0008] The GREAT eVENT product in 1 is comprised of multiple layers of corrugated plastic built up to a sufficient thickness to cover the tallest point of the profile of the roofing material beneath it. By virtue of the corrugations in the plastic, air may freely flow through the product 1 to the outside of the building envelope, thereby accomplishing the desired ventilation of the interior space.

[0009] The voids 2 are cut into the product 1 in order to allow the product 1 to nest snugly over the profile of the roofing material beneath it. Please note both the spacing and shape of these voids will vary depending on the profile of any given roofing material.

[0010] The membrane 3 is comprised of a mesh type non absorbent material permanently bonded product 1 on top and bottom. The purpose of membrane 3 is to help in shielding the building envelope from wind driven matter such as night be found in shallow sloped roofs or areas subjected to frequent high wind conditions. Membrane 3 is further cut at each void 2 to allow product 1 to nest snugly to roofing material. Please note that this membrane 3 may not be necessary in all cases to use in each application of product 1.

[0011] The adhesive strip 4 found on the bottom of product 1 is to aid in ease of installation during windy conditions. It is not intended to be used as a permanent adhesive nor as a sealant. Please note that it too may not be necessary in all cases to use adhesive strip 4 in each application of product 1.

[0012] The main benefits of the product 1 are ventilation ability, durability, ease of installation, and cost savings. Other applications and benefits of this product may well be found without substantial modifications thereto. 

I claim:
 1. A ventilation system for formed roofing materials in which the ventilation product is comprised of a corrugated material with voids in it to fit over the profile of the roofing material beneath it.
 2. A membrane bonded to the ventilation system in claim 1 that will allow air to pass through but will help restrict the passage of wind born matter.
 3. An adhesive strip on the bottom of the ventilation system in claim
